2D图形 Polygon多边形

• 创建多边形

  double[] points = {  
        0.0, 0.0,  
        100.0, 0.0,  
        100.0, 100.0  
  };// 三个点坐标  
  // 通过构造方法创建
  Polygon polygon = new Polygon(points);
  // 通过对象方法创建
  polygon1.getPoints().addAll(0.0, 0.0, 100.0, 0.0, 100.0, 100.0, 0.0, 100.0);
  

• 其他设置

  double[] points2 = {  
        0.0,0.0,  
        100.0,0.0,  
        100.0,100.0,  
        200.0,150.0,  
        100.0,200.0  
  };  
  Polygon polygon2 = new Polygon(points2);  
  polygon2.setFill(Color.valueOf("#ff9999"));  
  polygon2.setStrokeWidth(3);  
  polygon2.setStroke(Color.valueOf("#996699"));  
  polygon2.getStrokeDashArray().addAll(10.0, 10.0);  
  box.getChildren().add(polygon2);
